Reverse drive at a gearbox, with cogwheels, has a synchronizing ring with a groove around it to take a ring spring, facing the groove around the inner teeth of the reverse gear cogwheel for a rapid and quiet gear shift

摘要

The assembly to give a rapid and quiet shift into reverse gear, in a gearbox with cogwheels, has a synchronizing ring (2) with a groove (8) around it to take a ring spring (3). The inner tooth structure of the reverse drive cogwheel (1) also has a groove (7) around it, which lies opposite the groove of the synchronizing ring when it is not engaged. The depth of the synchronizing ring groove is at least equal to the diameter (d) of the ring spring.
